MINETEST RAILWAY CONNECTIONS SEARCH ENGINE

Description

MineTest Railway Connections Search Engine is tool which allows to search train connections between the railway stations of interest to us. It using MapServer and MapServer MOD to download train lines (defined earlier by mapserver:train blocks) and saved train lines (with distances and travel time) and connections between cities (based on train lines) to database.

It uses Floyd–Warshall algorithm to fast find path between start station and end station (show only one path), and undirected graph to find all paths between stations (note: if some city doesn’t have connection with graph, it causes freezing website or show server error 503 – Service Unavailable, so Floyd–Warshall algorithm fix it).

  • set_time_limit(60)
    • 60 [or any number] – max. time in seconds for executing code
    • Please don’t set 0 – its means any limits for executing code
    • 60 is ok, you can set lower number or higher but not too high
  • ini_set(‘memory_limit’, ‘512M’)
    • set max memory which may be used by script
